noon BUFFER.

This invention relates generally to door buffers and refers more particularly to those designed for cushioning the doors of vehicle bodies. p

One of the essential objects of the inventionis to provide a light-and durable construction that may be easily applied to a door jamb and is capable of holdingthe door against rattling while the vehicle body m is in motion.

A further object is to provide a buffer that is simple in construction and can be manufactured at a comparatively low cost.

Vith the above and other objects in view the invention consists in certain novel features of construction, combinations and arrangements of parts as will be more fully described and particularly pointed out in the appended claim.

In the accompanying drawing;

Figure 1 is a si e elevation of a portion of a vehicle body and showing a buffer construction embodying my invention applied thereto.

Figure 2 is a sectional view taken on the line 22 of Figure 1. y I

- Figure 3 is a sectional view taken on the line 3-3 of Figure 1.

Figure 4 is a top'plan view of the buffer construction with the cover plate removed.

-Referring.now to the drawing in which like characters of reference designate corresponding parts throughout the several yiews, 'the numeral 1 designates a door j amb preferably of a vehicle body, having an elongated recess or pocket 2 in which the casing 3 for the buffer blocks 4, is preferably held by means of suitable screws 5. This'casing is preferably stamped from a single sheet of metal and is substantially U-shape in cross section. To facilitate the machining operation during the process of construction, the end walls 6 of the casing are preferably rounded as shown best in Figure 4 of the drawing.

The buffer blocks 4 are preferably formed of rubber and are located at the opposite ends of the casing 3 so as to provide an intermediate passageway 7 extending. transversely of the casing. As shown, the outer ends of the blocks 4 are preferably rounded to conform to the rounded end walls of the casing, while the inner opposed ends of the blocks are preferably provided with flat faces 8 that are preferably parallel.-

In order that these blocks will effectively clishion the door when moved to a closed position, the outer side wall 9 of the casing is preferably provided with'a suitable opening l0 that is in alignment with the transverse passage-way 7 and is adapted to cooperate therewith for receiving an elongated tongue 11 projecting from a plate 12 secured to the outer edge of the door 13,

To prevent undue wear upon the opposed flahfaces 8 of the blocks, I preferably provide two wear plates 14 that extend across the flat faces 8 of the blocks and are provided at their opposite ends with substantially parallel arms 15 that embrace opposite sides of the blocks. These wear plates may be constructed of any suitable material but are preferably formed of sheet metal. Thus, when the door is closed, the blocks 4 will plates 14 to grip the sides cause the wear so that the door 13 will be of the tongue 11 prevented from rattling.

In order that the wear plates 14 will also serve to hold the blocks 4 against the curved end walls 6 of the casing, the arms 15 of the plates are preferably off-set inwardly within L-shaped recesses 16 in the opposed flat faces 8 of the blocks to provide shoulders 17 7 which bear against suitable lugs 18 that are pressed inwardly from the side walls of the casing,

For concealin the buffer blocks 4, I preferably provi e an elongated cover plate 19 that is preferably secured to'the casing 2 by means of the screws 5 that secure the casing to the door jamb. 'To accomplish this, the buffer blocks 4 are preferably provided with elongated openings 20 that register with suitable circular openings 21 and 22 respectively in the cover plate 19 and bottom 23 of the casing. Thus, only two screws are required .and the parts may be quickly and easily assembled. As shown at 24, the cover plate 19 is preferably embossed outwardly to receive te open edges of the cas- 100 ing, and is provided between the openings 21 with a transversely extending slot 25 that registers with the opening 10 and passageway 7 in the casing 3 and is adapted to receive the tongue 11 when the door is closed. 105

From the foregoing description it will be readily apparent that the'wear plates 1.4 for the resilient blocks 4 also serve as retaining means for holding the blocks in proper position for the casing. Moreover, no

the casing, resilient blocks and cover plate are held together by means of only two screws which also serve to secure the casing to the door jamb.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What I claim as my invention is:

In a door buffer. the combination with a pair of spaced bufl'er blocks, of a casing adapted to be stamped from a single sheet of metal having substantially parallel side walls and rounded and walls connecting into said side walls, wear plates positioned within said casing having the opposed faces thereof extending across end embracing the opposed faces of said blocks and having shoulders adjacent the sides of the casing, and arms projecting from said wear plates beyond the shoulders embracing the sides of said blocks,

an elongated cover plate secured to the casing. and headed elements extending through the cover plate, buffer blocks and casing for securing said parts to a support as a unit.

Tn testimony whereof I afiix my signature.

CLIFFORD J. WILLIAMS.
